Causes of Car Engine Ringing Sound – Normally, gasoline-engined cars will make noises in the engine. However, the sound that appears when the engine is working normally will be very much different from the sound of the engine being problematic and in abnormal conditions. One example is a car engine ringing sound. The ringing sound in a normal car engine will not be very audible, although the faint is still there. However, if the ringing sound that is heard is too loud. Of course, this condition indicates that your car engine is having problems.
Causes of Car Engine Ringing Sound
Try your gas up to 4000 rpm, if the ringing sound persists and even gets louder, this means the engine does have a problem. So what are the problems that occur and what is the cause of this tingling car engine?
The following article will explain the causes of car engine noises that often occur in car engines. Check out the full information below.
1. BEARING OR BEARING DAMAGE
The first and most likely cause of a car engine sounding is due to bearing or bearing damage. The cause of the ringing sound of a car engine due to bearings or bearings usually occurs because the bearing components in it have started to dry, wear out and become oblique. The worn and oblique condition on the inner surface of the bearing often causes a loud sound and tingling sound from the engine.
We can find the position of the bearing or bearing of this car engine right where the belt or timing belt is attached. In addition, the number of bearings and bearings in this machine is also very diverse, but usually more than one with different positions. Here are some bearings or bearings that we can find in car engines and are often the cause of car engines making ringing sounds.
- A belt tensioner pulley bearing is a bearing for belt adjustment pulleys (can be an A/C belt, alternator belt, or power steering belt).
- Timing belt tensioner bearings, which are bearings for timing belt adjustments, are located inside the timing belt.
- A bearing water pump is a bearing that is installed in the body of the water pump, usually replaced together with the water pump.
- A bearing pulley alternator (dynamo amperage), is a bearing that is installed in the body of the amperage dynamo. To replace this bearing you need to disassemble the alternator first.
In addition to the bearings above, on car engines there are also various names and functions of other bearings, of course, this is very dependent on the engine model of the engine manufacturer. However, the 4 bearings above generally represent the bearings in the car engine.
To find out which bearing is damaged, you need to use the services of an experienced technician so that the damage analysis can be precise. Usually, technicians use a tool such as a stethoscope to determine which bearing is faulty or if they have a lot of experience they can simply determine where the sound is coming from.
For the replacement process and the cost, there is a replacement that is fast and cheap. However, there is also damage that requires expensive replacement costs and a long time. It all depends on where the faulty bearing is located. For example, if the damaged bearing is only on the AC belt tensioner bearing or alternator, then the work can be done quickly with cheap replacement costs.
However, if the damaged bearing is on the inside of the timing belt or water pump, the replacement process can take a long time and be more expensive.
2. RADIATOR COOLING FAN IS INTERRUPTED
The radiator cooling fan that is disrupted can also be the cause of the ringing sound in the car engine. This condition usually occurs when the engine is already very hot (usually the car is driven for a long period of time or when stuck in traffic).
However, you need to make sure the sound is ringing because the sound that comes from the cooling fan can occur for two reasons:
If the ringing sound is loud and loud, this problem usually occurs because the radiator grille and AC condenser have started to become clogged or clogged with dust and dirt. As a result, the airflow becomes disturbed so that when the fan sucks air hard, it can make a whistling and roaring sound from the radiator cooling fan. Usually, if it has been cleaned, the ringing and roaring sound can be reduced and even returned to normal.

If the ringing sound that appears is shrill and sharp like iron scraping and its position is from the center of the cooling fan, this indicates that the bearings on the cooling fan motor are worn and dry. For this matter, a high-precision inspection is required so that there is no mistake in the estimation of repairs.
3. The RECTIFIER DIODE ON THE DYNAMO Ampere is BROKEN
The rectifier diode in the ampere dynamo is a component that functions to convert AC current into DC. That way, the electricity generated by the dynamo amperage can be used to supply electric current in the car, even to charge the battery.
When the rectifier diode is short or short, this damage will cause a tingling sound effect on the ampere dynamo due to the meeting of AC and DC currents. In addition, this condition will also cause the appearance of excessive heat on the dynamo amperage accompanied by a decrease in the charging voltage.
Generally, the sound is only heard when the engine is idle. Meanwhile, when gassed, the sound will disappear because the engine sound is disguised. To make sure again, with the engine running, open the hood, then make sure that the tingling sound comes from the amperage dynamo. After that, turn off the engine and remove the dynamo amperage socket then turn on the engine again. If the tingling sound disappears, it can be ascertained that the source of the sound is the rectifier diode.
That’s the article about the cause of the car engine sounding tingling that you can convey, hopefully, this article can be useful.
